Si-list subscribers,

Now that we are all back from our holiday breaks, I will repost the questions
below in the hope that some informative discussion can be generated. To date I
have received several "let me know what you find out" type responses. I expect
that some members of the SI-list subscriber community also support EMI/EMC
analysis work, and therefore attempt to utilize the same CAE tool vendors,
device models (IBIS, Spice, etc.) for both EMI/EMC and SI analysis. Is there a
better/alternative forum for posting these questions?

Thanks in advance for your input.
